IPC: H04M1/00
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To project a background in a higher contrast at night, etc., even when the surrounding of a door slave unit is dark, by digitizing output signals of a CCD camera, integrating and preserving the digitized output signals and then switching between the digitized output signals and the preserved integrated signals by means of a signal to detect the outline of a visitor from the digitized output signals. SOLUTION: A door slave unit 1 converts video signals of a CCD camera 102 into digital signals by an A/D conversion circuit 103 and preserves these signals in a memory 105 after integrating them by an integration circuit 104. A changeover switch 108 switches the digital signals to the integrated signals of the memory 105 based on the outline of a visitor that is detected from the digital signals by an outline detection circuit 107. Thus, signal processing is carried out to cut only the inside of the outline out of the integrated signals and to paste only the inside of the outline from the digital signals. Then a video signal f3 is transmitted via a D/A converter 109 and a modulation circuit 111. As a result, a clear image is obtained at the boundary part between the outline and the background of the visitor.

Title: Hammer drill
Inventor: SAKAMOTO YOSHIHIRO
IPC: B23B45/16
Filed: 1987-01-27
Abstract: PURPOSE:To prevent unnecessary energy consumption and generation of noise by controlling the transmission of power between a motor and a motion transforming member through a clutch means, and by controlling the pressing of a drill bit coupled to a clutch plate by a mechanically associating means, against a surface to be drilled, with the use of an electromagnet solenoid. CONSTITUTION:During no drilling is made, a clutch plate 26 is positioned on the forward side so as to release the coupling between the plate 26 and a motion transforming member 5. A reduction gear 24 is meshed with a pinion 21, and therefore the rotation of the motor 2 is transmitted to a drill bit 8 through an intermediate shaft 23, a spindle 31 and a key 39. However, the member 5 is isolated so that a piston 4 is not reciprocated. When the bit 8 is made to abut against a surface to be drilled, a striker 33 is retracted to mesh the plate 26 with the member 5 so that the reciprocating motion of the piston 4 is transmitted to the bit 8 through the member 5, an striking member 41 and the striker 33. Thus, when no drilling is made, the piston 4 does not reciprocated so that unnecessary energy consumption may be reduced and the generation of noise may also be prevented.
